Fossil notes 6th

Fossils provide clues about past environments and organisms. A fossil is any remains or evidence of living things from the past. Most organisms decay rather than become fossils, but fossils are more likely to form when an organism is buried quickly, especially if it had a hard structure like teeth or shells that could withstand decay. Fossils tell us about Earth's past environments, plants and animals by preserving evidence of organisms that lived long ago.
